"They contacted us to advise they had some concerns about some bracing elements to a group of buildings built under 11 separate consents, and were voluntarily undertaking work to remedy this," said council building control weathertightness and compliance manager Sally Grey.

"The works were not as a result of any actual failure of the buildings that we are aware of."

The repairs were due to be done early next month. The developer would then apply for retrospective certification.

Ms Grey said the council granted affected buildings code compliance certificates between October 2013 and June 2015 on the advice of experts.

Council building control general manager Ian McCormick said the council relied on the expertise of certified engineers to confirm work met the building code.

The rest of Kensington Park's buildings had been checked and met design standards, he said.

"We have moved quickly to address the issue affecting the 11 buildings. Owners of the homes have moved out pending remediation work. Remediation will fully address the issues identified."

The urgent repairs were being peer reviewed and would cost between $20,000 and $40,000 per building at no cost to residents. Property owners were expected to be back in their homes by early next month.
